Though Bishop told radio station WWJ that he's uninjured, multiple people have been shot, including Rep. Steve Scalise, R-La., the House Majority Whip, and multiple Capitol Hill police officers.

U.S. Rep. Jack Bergman, R-Watersmeet, and U.S. Rep. John Moolenaar, R-Midland, were also at the scene and uninjured, Bishop said this morning. Moolenaar's office released a statement: "This morning, Congressman John Moolenaar attended baseball practice. He was uninjured in the shooting that took place. He asks that you keep those injured in this act of cowardice in your thoughts and prayers."

“As we were standing here this morning, a gunman walked up to the fence line and just began to shoot. I was standing at home plate and he was in the third base line,” Bishop said. “He had a rifle that was clearly meant for the job of taking people out, multiple casualties, and he had several rounds and magazines that he kept unloading and reloading.”

“The only reason why any of us walked out of this thing, by the grace of God, one of the folks here had a weapon to fire back and give us a moment to find cover. We were inside the backstop and if we didn’t have that cover by a brave person who stood up and took a shot themselves, we would not have gotten out of there and every one of us would have been hit — every single one of us,” said Bishop. “He was coming around the fence line and he was looking for all of us who had found cover in different spots. But if we didn’t have return fire right there, he would have come up to each one of us and shot us point-blank.”

"I was on deck, about to hit batting practice, when I heard a 'blam,'" Brooks said. Brooks said people scattered and that Scalise was among those who were shot.

"He was not able to move under his own power. He was dragging his body from second base," Brooks said. "There was not a whole lot we could do. He was shot in the hip. I think it was not a life-threatening wound."
